Mechanical Energy
Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.
Explanation:
Mechanism energy is the energy associated with the position and motion of an object. Therefore it is also the summation of the kinetic and potential energies of the object.
In the muscles, to have movement, the chemical bonds in ATP is broken to enable the sliding action of the myosin and actin fibres of a sarcomere (the basic unit of muscle). This sliding action is responsible for contraction of muscle. The coordinated contractions and relaxations of sarcomeres on muscles result in movement which translates to mechanical energy.
This process is never 100% efficient with some energy lost as heat energy.

Answer:
Oiling is done on a regular basis to sewing Machine because in the machine there are lots of machinery parts i.e. wheels and axels, etc. which are in continuous use and they possess so much frictional force between them that wear tear may be observed in those parts.
The density of it would be 57. Do the math and apply the formula to it and you would get this answer.
Given that acids burns and the reactions of some metals with acids are violent, you have to protect agains spills and splashes that can seriously harm you: your eyes, your hands, your arms, your feet, even your clothe.
So you shall use:
- Safety glasses (googles)
- Chemical gloves
- Lab coat
- Closed shoes
